Iftar is the meal when people break the fast at sunset during Ramadan and is an opportunity for Muslims to show generosity. It can take a number of forms and non-Muslims can also be invited to partake in this hospitality.
When sharing your faith with your Muslim friends it is important to know about the basics of their beliefs and practices and to share in a manner that is sensitive to their culture and individuality. Most importantly, remember that your are their friend and view the relationship in that light.
